I have a 1962 GMC step side that I just finishing stripped down to the cab and frame I plan on putting air ride suspension on it. The only thing with that is I find a lot of suspension parts for a 63 and newer but not for a 62. Does anyone know the difference between them or can I just use the 63 aftermarket part. thanks for any info in advance

I am guessing it is due to the torsion bar supsension in the 1960-1963 trucks. Different spindle type and no coil spring setup for the air ride bags to interchange with.

This thread discusses the removal of the Torsion bar and cupping the lower A arm to add an air bag. Not sure if that's what you were trying to accomplish or do you just wish to rebuild as stock for now?

SHOWBOAT, this is Lewis Matkin. If you have front coil springs, chances are that the truck was damaged at some time in its life and the cab was replaced with a 62 cab. the 63 was the first year front coil springs were available on a gm truck. Gmc's would have been equipped with rear leaf springs.
